To find how many more kilograms is the mass of the Golden Gate Bridge than the mass of the Eiffel Tower, we subtract the mass of the Eiffel Tower from the mass of the Golden Gate Bridge.
Mass of Golden Gate Bridge - Mass of Eiffel Tower = 8.05 ⋅ 10^8 kg - 9.16 ⋅ 10^6 kg
To subtract these numbers in scientific notation, we need to make sure the exponents are the same. To do this, we can rewrite the mass of the Eiffel Tower in scientific notation with the same exponent as the mass of the Golden Gate Bridge.
Mass of Eiffel Tower = 9.16 ⋅ 10^6 kg = 0.916 ⋅ 10^7 kg
Now we can subtract the two masses:
8.05 ⋅ 10^8 kg - 0.916 ⋅ 10^7 kg = 8.05 ⋅ 10^8 kg - 0.916 ⋅ 10^7 kg = 8.05 ⋅ 10^8 kg - 0.916 ⋅ 10^8 kg = (8.05 - 0.916) ⋅ 10^8 kg
(8.05 - 0.916) ⋅ 10^8 kg = 7.134 ⋅ 10^8 kg
Therefore, the mass of the Golden Gate Bridge is approximately 7.134 ⋅ 10^8 kilograms more than the mass of the Eiffel Tower.
The mass of the Eiffel Tower is about 9.16 ⋅ 10^6 kilograms. The mass of the Golden Gate Bridge is 8.05 ⋅ 10^8 kilograms.
